Suggestion - extending UAB with XDelta, BitTorrent

I have two suggestion:
1) extend UAB with BitTorrent protocol - on server there will be only metainfo file and original release file - new implementation of IDownloader (http://www.bittorrent.com)
2) new version of apps will be released as XDelta diff files - new implementation of IActivationProcessor (http://sourceforge.net/projects/xdelta/)

By using application which uses UAB user will be seeding diff files.
What you think about it?
